37 killed in Indian Kashmir attack

At least 37 Indian paramilitary soldiers were killed on Thursday in Indian-administered Kashmir in one the deadliest attacks on government forces there, police said.

The suicide bombing outside Srinagar claimed by an Islamist group is likely to ratchet up tensions between nuclear-armed arch rivals India and Pakistan, with New Delhi long accusing Islamabad of supporting militants.

Photos showed the blackened, mangled remains of at least one vehicle littered across the highway.

Reports said that there were 350 kilos (770 pounds) of explosives used.

Local media reports said the Pakistan-based Jaish-e-Mohammed Islamist group claimed responsibility.

A spokesman for the group told a local news agency that the "suicide attack" was carried out by Aadil Ahmad, alias Waqas Commando, a known militant from the area.

After the attack, hundreds of government forces cordoned around 15 villages in the district the bomber came from and started searching house-to-house, a police officer and witnesses said.

The last major car bombing, which killed 40 people including three suicide attackers, was also carried out by Jaish-e-Mohammed, in 2001. The target was the local parliament building in Srinagar.

The US condemned the attack in "the strongest terms" on Thursday, and called on "all countries...to deny safe haven and support for terrorists."

State Department deputy spokesman Robert Palladino said Washington was "resolutely committed to working with the Indian government to combat terrorism in all its forms".

The attack surpasses one in 2016 that was the biggest in 14 years, claiming the lives of 19 soldiers in a brazen pre-dawn raid by militants on the Uri army camp.

India blamed militants in Pakistan for that attack, and responded with strikes across the heavily-militarised Line of Control, the de-facto border dividing the nuclear-armed nations.

The "surgical strikes" several kilometres (miles) inside Pakistan-controlled Kashmir remain a source of national pride for Modi's government and were the subject of a rip-roaring recent Bollywood film.

India's foreign ministry, in a statement late Thursday, blamed Pakistan.

"This heinous and despicable act has been perpetrated by Jaish-e-Mohammed, a Pakistan-based and supported terrorist organisation proscribed by the United Nations and other countries," the foreign office said.

"India is firmly and resolutely committed to take all necessary measures to safeguard national security. We demand that Pakistan stop supporting terrorists and terror groups operating from their territory," it added.

Islamabad, however, rejected the suggestion that it was involved and said it had "always condemned acts of violence."

"We strongly reject any insinuation by elements in the Indian media and government that seek to link the attack to Pakistan without investigations," the Pakistan foreign ministry said.

Before Thursday's violence, the biggest attack on Indian forces was in May 2002, when militants attacked an Indian army camp in Kaluchak in Jammu city, killing 34 people, including family members of soldiers.

Kashmir has been divided between India and Pakistan since independence. Rebels have been fighting for an independent Kashmir, or a merger with Pakistan, for 30 years.

Last year was the deadliest in a decade, with rights monitors saying almost 600 people died, most of them civilians. Thousands more have been maimed in recent years by pellet-firing shotguns used by Indian forces.

Pakistan says it only provides diplomatic support to Kashmiris' right to self-determination.
